Immune effector cell-associated neurotoxicity syndrome (ICANS) is a serious complication observed in patients receiving advanced immunotherapies such as bispecific antibodies and CAR-T cell therapies. Although the Immune Effector Cell-Associated Encephalopathy (ICE) score is commonly used to assess ICANS severity, its diagnostic accuracy can be compromised by factors such as concomitant medications, underlying comorbidities, and other external influences. This case report discusses a patient with diffuse large B-cell lymphoma who developed ICANS while receiving Epcoritamab.

Mucormycosis is a severe mold infection primarily affecting immunocompromised patients. Neutropenia, steroid use, hyperglycemia, and diabetes are recognized as significant risk factors. Cunninghamella species are rare pathogenic fungi associated with high mortality rates and multidrug resistance.

Epcoritamab, a bispecific T-cell engager (BiTE) antibody targeting CD3 and CD20, has shown significant efficacy in treating refractory diffuse large B-cell lymphoma (DLBCL). However, its use can lead to severe side effects, such as tumor flare. Here, we report the case of an 84-year-old male with relapsed DLBCL who developed fatal unilateral pleural effusion following Epcoritamab treatment.

Article Synopsis
  • Primary leptomeningeal malignant lymphoma (PLML) is a rare form of primary central nervous system lymphoma (PCNSL) with no established treatment due to its uniqueness.* -
  • A case study of a 46-year-old male with PLML showed complete remission after treatment with a combination of chemotherapy (R-MPV and intrathecal agents) and autologous stem-cell transplantation (ASCT) using a thiotepa regimen.* -
  • A literature review indicated that ASCT has been successfully used in three reported cases of PLML, suggesting it may be an effective consolidation therapy, but more research is necessary to develop standardized treatment guidelines.*

Pear pollination is performed by artificial pollination because the pollination rate through insect pollination is not stable. Pollen must be collected to secure sufficient pollen for artificial pollination. However, recently, collecting sufficient amounts of pollen in Japan has become difficult, resulting in increased imports from overseas.

Article Synopsis
  • * In a reported case, plasma cells appeared in a patient's blood during treatment, but they were deemed reactive and disappeared on their own, leading to successful hematopoietic recovery.
  • * This case is significant as it is the first documented instance of reactive plasmacytosis occurring during immunosuppressive therapy for aplastic anemia, suggesting that it could indicate a positive treatment response.

Although alectinib is effective for relapsed or refractory ALK-positive anaplastic large cell lymphoma (ALCL) and has a favorable safety profile, its role as a bridging therapy for allogeneic hematopoietic stem cell transplantation (allo-HSCT) and the role of allo-HSCT itself in this setting are unknown. A 35-year-old man with ALK-positive ALCL experienced relapse after first-line therapy with CHOP. Brentuximab vedotin led to partial response and high-dose chemotherapy combined with autologous HSCT was performed.

Pericytes are mesenchymal cells that surround the endothelial cells of small vessels in various organs. These cells express several markers, such as NG2, CD146, and PDGFRβ, and play an important role in the stabilization and maturation of blood vessels. It was also recently revealed that like mesenchymal stem cells (MSCs), pericytes possess multilineage differentiation capacity, especially myogenic, adipogenic, and fibrogenic differentiation capacities.
